F This chapter contains information about other problems that are known @ to impact DCPS and patch kits (ECOs) that address some of these C problems. Patch kits for supported versions of OpenVMS are listed, 8 although there may be kits available for other versions.
7 You can obtain these patch kits (or an update to them):
E In certain situations, DCPS symbiont processes can consume excessive F CPU time. For example, when the time is moved forward at the Standard G Time/Daylight Savings Time adjustment, multithreaded processes such as G DCPS went into a tight CPU loop. Stopping and restarting the processes resolved the problem.
A This problem can happen again at the next Standard Time/Daylight > Savings Time adjustment unless the following patch is applied:
G If DTSS is used to synchronize time, the following DECnet patch should also be applied:
E When initializing and starting an autostart DCPS queue that uses the E Raw TCP protocol, the queue manager can fail with an "invalid device name" error.

+ The following patch kit fixes this problem:
F All sites running DCPS as a multistreamed process on OpenVMS V7.1 and 9 earlier should install the Queue Manager Remedial Update.
+ The Queue Manager remedial update kits are:
E This update corrects problems that cause the START /QUEUE command to E hang under certain circumstances when operating with a multistreamed C symbiont. The release notes provided with the kit describe all the F problems fixed by this update. After installing this update, you need . to reboot your system to enable these changes.
D If this update is not installed, a queue running in a multistreamed D process that is stopped with STOP /QUEUE /RESET and quickly started H with START /QUEUE will hang. Also, the following message will sometimes be written to OPCOM:
|
" C %DCPS-F-STREAMUSE, Request 4 for Stream Id n ignored. ' Not consistent with symbiont state |
E To recover, issue a Ctrl/Y to return to the DCL prompt, then issue a C STOP /QUEUE /RESET again, wait a few seconds, and try to start the E queue again. To avoid this problem, install the queue manager update. n 4.4 I/O Errors for Serially-Connected Printers
D There is an OpenVMS terminal driver problem that may result in your G printer reporting I/O problems when connected to a serial port of your H OpenVMS system. You may see the problem with OpenVMS Alpha V6.2 through H V7.0, and with OpenVMS VAX V5.5 through V7.0, depending in part on what " kind of serial port you are using.
C The problem is that the terminal driver sometimes does not respond B quickly enough to an XOFF request from the printer to prevent the F printer from losing data. This problem is fixed in OpenVMS Alpha V7.1.
+ The following patch kit fixes this problem:
G The DCPS symbiont can abort with an ACCVIO or BADPARAM error, possibly F also indicating the CMA (DECthreads) facility. Other software on your F system, including HP TCP/IP Services for OpenVMS and anything layered upon DECthreads, may also fail.
G The problem is related to a long-standing OpenVMS restriction of fewer B than 10,000 days in a delta-time value. POSIX-related software in F particular, using the UNIX® reference date of 1 January 1970, can encounter this limit.
* The following patch kits fix this problem:
F When setting up a DCPS queue using a Raw TCP/IP connection, check the E documentation for your network interface card (NIC), print server or F terminal server to determine the number of its Raw TCP/IP port (if it G has one). The Raw TCP/IP port must support bidirectional communication , between the printer and your OpenVMS system.
Table A-1 shows the port numbers for some commonly-used devices.
